Giant monopole resonance strength in Si-28
(American Physical Society, 1998)
The giant resonance region in Si-28 was studied with inelastic scattering of 240 MeV alpha particles at small angles including 0 degrees. The giant resonance peak extended from E-x=12 MeV to 35 MeV and E0 strength corresponding ...
Pion interferometry in Au plus Au and Cu plus Cu collisions at s(NN)=62.4 and 200 GeV
(American Physical Society, 2009)
We present a systematic analysis of two-pion interferometry in Au+Au collisions at s(NN)=62.4 GeV and Cu+Cu collisions at s(NN)=62.4 and 200 GeV using the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The ...
Deuteron-nucleus collisions in a multiphase transport model
(American Physical Society, 2003)
Using a multiphase transport model, we study pseudorapidity distributions and transverse momentum spectra in deuteron-gold collisions at RHIC. We find that final-state partonic and hadronic interactions affect the transverse ...
Subthreshold Antiproton Production in Nucleus-Nucleus Collisions
(American Physical Society, 1994)
Antiproton production in nucleus-nucleus collisions at energies below the threshold for its production from the nucleon-nucleon interaction in free space is studied in the relativistic Vlasov-Uehling-Uhlenbeck model. The ...
Nuclear modification factor of nonphotonic electrons in heavy-ion collisions, and the heavy-flavor baryon-to-meson ratio
(American Physical Society, 2009)
The nuclear modification factor R(AA) of nonphotonic electrons in Au + Au collisions at root(S)NN = 200 GeV is studied by considering the decays of heavy-flavor hadrons produced in a quark coalescence model. Although an ...
Transport Model with Quasipions
(American Physical Society, 1993)
We extend the normal transport model to include the medium effect on pions by treating them as quasiparticles. The property of the quasipion is determined using the delta-hole model. Modelling heavy-ion collisions at ...
Kaon Production from Hot and Dense Matter Formed in Heavy-Ion Collisions
(American Physical Society, 1991)
In heavy-ion collisions, kaons can be produced from baryon-baryon, meson-baryon, and meson-meson interactions. Simple meson-exchange models are introduced to study kaon production from these processes in the free space. ...
Measurement of Spin-Correlation Parameters all and Asl in P-P Elastic-Scattering from 500 Mev to 800 Mev
(American Physical Society, 1992)
The spin-correlation observable A(LL) for p-p elastic scattering has been measured at energies 589, 640, 692, 743, and 793 MeV, over a c.m. angular range between 20-degrees and 100-degrees. The spin observable A(SL) was ...
Anisotropic flow in Cu plus Au collisions at root s(N N)=200GeV RID A-2398-2009
(American Physical Society, 2006)
The anisotropic flow of charged hadrons in asymmetric Cu+Au collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Compared with previous results for symmetric Au+Au collisions, charged ...
Medium Effects on the Rho-Meson
(American Physical Society, 1993)
The property of a rho meson in dense nuclear matter is studied using the QCD sum rule. The spectral function appearing on the hadronic side of the sum rule is evaluated in the vector dominance model that takes into account ...
